The invention provides an acoustic resonance excitation device and an application thereof, which are used for solving the technical problems of complex structure, inconvenience in control and high cost of an oscillation starting mechanism of an existing acoustic resonance mixer. Firstly, the eccentric vibration starting mechanisms are arranged on the two sides of the arc-shaped middle vertical plate in the middle of the supporting bottom plate, the rotary power mechanism is used for providing power in the opposite directions for the two eccentric vibration starting mechanisms, exciting force generated in the vibration starting process counteracts in the horizontal direction, loads in the horizontal direction are reduced, and noise is lowered; secondly, the two eccentric oscillation starting mechanisms can be controlled only through one rotary power mechanism, the structure is simple, operation is convenient, and the device is suitable for large-scale application; finally, the device can be applied to a three-mass acoustic resonance mixer or a two-mass acoustic resonance mixer as required, and uniform mixing of materials is realized by stably outputting excitation force in the vertical direction.
Description
technical field [0001] The invention relates to the technical field of acoustic resonance mixers, in particular to an acoustic resonance excitation device and its application. Background technique [0002] The acoustic resonance mixer uses the high-intensity vibration generated by the resonance of the mechanical system to excite low-frequency and high-intensity sound waves in the multiphase flow through high-intensity vibrations, and achieves the purpose of resonance mixing under the excitation of sound waves and the system. [0003] The existing vibrating mechanism adopts 4 or 6 servo motors in parallel to drive the counterweight to vibrate. Since the four motors operate independently of each other, the control logic is more complicated, and the four / six servo motors take up a lot of space and are expensive, and the product economy is low. [0004] Therefore, it is urgent for researchers to design a vibration mechanism for acoustic resonance mixers with simple control stru...
